What Month Is Winter __hot__

While the solstice marks the minimum sunlight, there is a phenomenon called "seasonal lag." The ground and oceans retain heat. This means that even though solar radiation is weakest around December 21st, the coldest average temperatures usually occur in mid-to-late January. Therefore, lumping December, January, and February together creates a neat box that perfectly captures the "thermal winter."

This grouping is based on the annual temperature cycle. In the Northern Hemisphere, the three-month window of December through February encompasses the coldest period of the year. Because the calendar dates are fixed, meteorological winter allows scientists to calculate seasonal averages (e.g., "average winter temperature") easily without worrying the fluctuating dates of solstices or equinoxes. what month is winter

In regions such as Australia, New Zealand, South Africa, and South America, the calendar is flipped. Infographic: Meteorological and astronomical seasons - NOAA While the solstice marks the minimum sunlight, there

But if you ask a meteorologist, an astronomer, a Celtic farmer from 500 BCE, or a biologist tracking hibernation cycles, you will get four completely different answers. In the Northern Hemisphere, the three-month window of
